KiwiSaver contributions come from three sources: you, your employer, and the government. Understanding how each works — and how to optimise each one — has a larger impact on your retirement balance than fund selection in most cases.
The Three Contribution Sources
Your contributions are deducted from gross salary at your chosen rate: 3%, 4%, 6%, 8%, or 10%. The minimum is 3%. On a $70,000 salary, that’s $2,100/year at 3% — or $7,000/year at 10%.
Employer contributions are a mandatory minimum of 3% of your gross salary, paid on top of your wages (not deducted from them). ESCT (Employer Superannuation Contribution Tax) is deducted from employer contributions at your tax rate before they reach your account.
Government Member Tax Credit (MTC) — IRD contributes up to $521.43/year. To receive the full amount, you must contribute at least $1,042.86 over the KiwiSaver year (1 July–30 June). This is effectively a 50% return on contributions up to the threshold — guaranteed.
Contribution Rate Comparison
| Rate | $60,000 salary | $80,000 salary | $100,000 salary |
|---|---|---|---|
| 3% | $1,800/yr | $2,400/yr | $3,000/yr |
| 4% | $2,400/yr | $3,200/yr | $4,000/yr |
| 6% | $3,600/yr | $4,800/yr | $6,000/yr |
| 8% | $4,800/yr | $6,400/yr | $8,000/yr |
| 10% | $6,000/yr | $8,000/yr | $10,000/yr |
Plus your employer’s matching 3% on top of each figure above.
What Rate Should You Choose?
The right rate depends on your financial situation, but as a starting point:
- 3% — minimum; appropriate if paying down high-interest debt
- 4% — marginal improvement, often the breakeven with take-home pay impact
- 6% — recommended for most people not in financial hardship
- 8–10% — ideal for those focused on retirement, or catching up for lost years
